The best AI email assistants in 2026
"AI email assistant" means two quite different things. Most are inbox helpers: they sit in your Gmail or Outlook, sort the mail, sum up long threads and write drafts in your voice, and you press send. A few are assistants that handle email jobs for you: they send, wait for the reply, and chase it on Thursday if nobody answers.
Which kind you want depends on one question: do you want to stay in your inbox and keep your hand on every send, or do you want the job off your plate? We cover both below, and say plainly which suits whom.
The list
Your Own AI Assistant · Best for handing email jobs off entirely
This one isn't an inbox app. It's an assistant with its own email address, so you can tell it "get three quotes for clearing the gutters and let me know by Friday" and it emails the companies, reads their replies as they land, chases the slow one and texts you the comparison. Businesses can write to it directly.
Connect your Gmail or Outlook with one button and it can also read what comes in and reply as you. It sets follow-ups for the time you choose and keeps notes about you between jobs, and it can phone a business if email is getting nowhere.
Good for: Owners and busy people who want email jobs done, not drafted.
Watch out for: There's no inbox app to browse, and plans start at $99 a month after the free trial (no card, up to $250 of use or 14 days). Check anything important it sends in your name.
Price: Free trial (no card); then from $99 a month
Superhuman Mail · Best for getting through a busy inbox fast
Superhuman Mail sits on top of Gmail or Outlook and is built for speed: split inbox, snooze, send later, follow-up reminders. Its AI labels and archives low-priority mail, writes drafts in your style, sums up every thread in one line and answers questions across your inbox, calendar and the web.
You stay in your own inbox and decide what goes out. Its Mail page says the AI can send for you if you choose.
Good for: People who live in email all day, on Gmail or Outlook.
Watch out for: Auto Drafts and Ask AI are on Business only ($33 per member a month billed yearly), and the Mail plans page shows no free trial.
Price: Mail Starter: $25 per member per month, billed annually; Mail Business: $33 per member per month, billed annually; Mail Enterprise: Custom
Shortwave · Best for Gmail users
Shortwave is an email app built around Gmail. Its assistant writes in your voice, searches your mail by meaning ("what did the accountant say about the tax return?"), puts a summary on each email, turns emails into to-dos and helps schedule meetings.
AI filters let you write sorting rules in plain English. Plans start at $30 a seat a month, with a 14-day free trial.
Good for: Gmail users with a lot of mail who like asking in plain English.
Watch out for: Its pages don't confirm Outlook support, and AI use has a daily quota (about 150 to 300 standard requests on Business).
Price: Business: $30 per seat per month; Premier: $45 per seat per month; Max: $120 per seat per month
Fyxer · Best if you want to approve every send
Fyxer works inside Gmail or Outlook. It sorts mail into labels and writes reply drafts that sound like you, and it never sends on its own: you review and press send. It also joins Zoom, Meet and Teams calls to take notes and sends you briefings.
There's a free plan, and Pro is $49 a person a month ($37 billed yearly).
Good for: People who want drafts waiting but full control of what goes out.
Watch out for: The free plan leaves out its main features: automatic drafts, inbox sorting and Flows.
Price: Free: $0; Pro: $49 per person per month ($37 billed yearly); Team: $99 per person per month ($64 billed yearly)
Gemini · Best low-cost add-on for Gmail
If you already use Gmail, Gemini works inside it (and inside Docs) from the Google AI Plus plan at $4.99 a month. It helps with your mail and documents without a new app.
Good for: Gmail users who want a little help for very little money.
Watch out for: It works inside your Gmail with no address of its own, and its Tasks aren't offered in the UK or EU.
Price: Free: $0; Google AI Plus: $4.99/month; Google AI Pro: $19.99/month
Microsoft Copilot · Best for Outlook and Microsoft 365
With a Microsoft 365 plan, Copilot works inside Outlook, Word and Excel. On Microsoft 365 Premium ($19.99 a month, with a one-month free trial), Cowork can draft and send email and manage your calendar.
Good for: People and small offices already on Outlook and Microsoft 365.
Watch out for: Cowork for personal accounts is still in preview, and Microsoft warns it may make mistakes.
Price: Copilot (free): $0; Microsoft 365 Personal: $9.99/month or $99.99/year; Microsoft 365 Premium: $19.99/month or $199.99/year
Howie · Best for scheduling over email
CC Howie on an email thread and it reads the conversation, checks your calendar, offers times, follows up when people go quiet and sends the invite. You can text it too.
It starts at $25 a month with $25 of free credits; an assistant address at your own company's domain is $20 a month extra.
Good for: Anyone tired of "what time works for you?" emails.
Watch out for: It's mainly a scheduler, and its page lists Google Calendar but doesn't say Outlook.
Price: Team: from $25/month; Custom assistant email (add-on): +$20/month; Enterprise: Custom

How we chose
We asked every tool the same questions. Does it just draft, or can it send, and does it ask first? Can it follow up days later without you prompting it? Does it work with Gmail, Outlook or both? Does it have an address of its own that other people can write to? And what do the features you actually want cost, not just the cheapest plan?
Every price and feature comes from the maker's own pages, checked on the date at the top of this page. Inbox apps and do-it-for-you assistants solve different problems, so we've labelled each pick for the job it does best.
